(1988), published in FEBS Letters , which found that GHK-Cu exposure at nanomolar concentrations in primary fibroblast cultures produced measurable increases in collagen synthesis relative to untreated controls.[5] This established the peptide's basic identity as a fibroblast-activating signal and prompted the wave of ECM-focused research that followed

GHK-Cu is a copper-binding tripeptide widely studied for its involvement in collagen synthesis, antioxidant activity, and gene expression related to tissue remodeling

When GHK-Cu and AHK-Cu are used in coordinated protocols, their distinct mechanisms reinforce each other and allow for more precise and effective outcomes
